Anti-reflective glass with ultra-large panel and preparation method thereof

Abstract

The invention provides anti-reflective glass with ultra-large panel and preparation method thereof. The anti-reflective glass comprises a glass substrate and a film-plating layer, wherein the film-plating layer is attached on the outer surface of one side of the glass substrate; the anti-reflective glass is characterized in that the film-plating layer comprises a first-layer silicon nitride layer,a second-layer silicon oxide layer, a third-layer silicon nitride layer and a fourth-layer silicon oxide layer which are fitted together in sequence from the glass substrate to an air surface; the thickness of the first-layer silicon nitride layer is 10nm to 16nm; the thickness of the second-layer silicon oxide layer, is 10nm to 20nm; the thickness of the third-layer silicon nitride layer is 10nmto 15nm; the thickness of the fourth-layer silicon oxide layer is 100nm to 120nm. According to the anti-reflective glass provided by the invention, the film-plating layer has high temperature resistance; after the film-plating layer is toughened for about 500s at the temperature of 700 DEG C, a film layer is not burnt by high temperature and the surface optical performance is consistent to that of a film layer which is not toughened. A film-layer structure is optimized so that needed optical performance can be obtained and the glass also can be toughened.

Description

technical field [0001] The invention relates to the application of magnetron sputtering coated glass to the field of decorative glass and architectural glass, in particular to a super-large surface anti-reflection glass and a preparation method thereof. Background technique [0002] Ordinary anti-reflection glass can only be tempered first and then coated. The film layer cannot be heated at high temperature. After heating, there will be serious peeling phenomenon, and the color of the glass surface will change greatly, so the plate surface is relatively small, and the long-distance transportation cost is high. ,high cost. And this kind of super-large anti-reflection glass solves the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the anti-reflection glass has a small surface and cannot be tempered, and provides an anti-reflection glass with a super large surface and a preparation method thereof.
